Patent application number | Description | Published |
20110310790 | WIRELESS COMMUNICATIONS SYSTEM, WIRELESS TERMINAL DEVICE, AND CHANNEL SWITCHING METHOD - A throughput measurement section measures network throughput of communications between a wireless device and an access point. A determination section determines whether the measured throughput satisfies a predetermined value. A channel switching section switches channels used for wireless communications between the wireless device and the access point if the determination section determines that the measured throughput does not satisfy the predetermined value. | 12-22-2011 |
20120005553 | TRANSMITTING APPARATUS AND TRANSMISSION METHOD - A transmitting apparatus for transmitting user data, includes: an establishing section that establishes three or more transmission paths for a receiving apparatus; a first generation section that generates a user data unit which includes user data to be transmitted to the receiving apparatus; and a second generation section that generates an error correction data unit which includes error correction data to be used for error correction of the user data to be transmitted to the receiving apparatus. At least one of the three or more transmission paths transmits the error correction data unit, and at least two of the three or more transmission paths transmits the user data unit. | 01-05-2012 |
20120026996 | COMMUNICATIONS DEVICE FOR PERFORMING WIRELESS COMMUNICATIONS, WIRELESS COMMUNICATIONS SYSTEM, WIRELESS COMMUNICATIONS METHOD, AND STORAGE MEDIUM - A communications device for performing wireless communications includes: a data receiving section for receiving data by wireless communications; a data transmitting section for transmitting data by wireless communications; a mode switching section for switching an operation mode of the communications device between a first mode in which power is supplied to the data transmitting section, and a second mode in which power consumption in at least the data transmitting section is minimized over that in the first mode; and a determination section for determining whether the data receiving section has received designated data. The mode switching section switches the operation mode of the communications device from the second mode to the first mode if, in a state in which the communications device is in the second mode, the determination section has determined that the data receiving section has received the designated data. | 02-02-2012 |
20120030466 | RELAY DEVICE, WIRELESS COMMUNICATIONS DEVICE, NETWORK SYSTEM, PROGRAM STORAGE MEDIUM, AND METHOD - A relay device first uses latest authentication data to determine whether request-authentication data transmitted from a wireless communications device is valid. If the latest authentication data is used to determine that the request-authentication data is valid, the relay device carries out relayed communications with the wireless communications device. If the latest authentication data is used to determine that the request-authentication data is invalid, the relay device next uses a former authentication data to determine whether the request-authentication data is valid. If the former authentication data is used to determine that the request-authentication data is valid, the relay device provides the wireless communications device with the latest authentication data to update authentication data in the wireless communications device. | 02-02-2012 |
20120059945 | Data-Transfer Method and Terminal - A first terminal connectable to a wireless LAN pre-stores utilization information required in order for a terminal to utilize the wireless LAN. At least one of either the first terminal, or a second terminal connectable to the wireless LAN, determines whether a predetermined operation requesting data transfer is present in the one terminal, and on the basis of the predetermined operation the first terminal transfers its stored utilization information via wireless means to the second terminal. The second terminal stores the utilization information transferred from the first terminal. | 03-08-2012 |
20120213110 | COMMUNICATION CHANNEL SELECTION DEVICE, METHOD, AND COMPUTER PROGRAM PRODUCT - A communication channel selection device, method and computer program product select a wireless communication channel among a plurality of communication channels with partially overlapping bandwidths in a frequency range available for use by an access point. A channel detector detects a busy channel used by another access point different from the access point. A signal strength detector detects a received signal strength of a wireless radio wave output from the another access point in the busy channel detected by the channel detector. A channel selector checks for a presence of a non-interfering channel that does not interfere with the detected busy channel, and when the channel selector does not detect the presence of the non-interfering channel, the channel selector selects the communication channel to be used by the access point based on the received signal strength of the wireless radio wave output in the busy channel. | 08-23-2012 |
20120287817 | APPARATUS, METHOD AND COMPUTER PROGRAM PRODUCT FOR REPLICATING SETTINGS INFORMATION - The apparatus, method and computer program product provide obtain settings information on a network connection set in a first network device; a settings information storage unit that stores the obtained settings information; a configuration information acquirer that obtains configuration information including information about the second network device; and a generator that selects at least part of settings information corresponding to the obtained configuration information among the settings information stored in the settings information storage unit, and utilizes the at least part of the settings information to generate replicate information used to replicate the settings information to the second network device so as to provide a network connection for the second network device. | 11-15-2012 |
20140313992 | SYSTEM AND INFORMATION PROCESSING APPARATUS - An information processing apparatus that selects a channel recommended to be used upon receiving a notification of a detection result indicating that a first wireless communication device among a plurality of wireless communication devices has detected a specific radio wave; and transmits channel information indicating the recommended channel a second wireless communication device among the plurality of wireless communication devices located near the first wireless communication device. | 10-23-2014 |
